In my other thread, I considered making this a summoner feat or archetype (and the archetype seems ok to me, but I haven't gotten many comments). I wanted to ask though, is there any other way to go about this? Are there any already written material (feats, spells, archetypes, etc.) that can do something similar (first or third party)?
Thanks.
Does no answer mean there's no RAW way to do this?
I would say that a spell is a better candidate than a feat or archtype.
Thanks for the input.
Would changing a creature's type be a Transmutation spell? I imagine this would be a summoner-only spell. Would a 2nd level spell (4th level summoner) be ok?
I'm not sure how to balance the changes the creature would undergo though (such as the improved saves of a dragon-type).
